. The Schedule referred to in thesemetter's Patent and making pari: of the samel Be it knownthat I, Rox/AL J OUSHING, ofvBowdoinham, in the county of Sagadahoc, and State of Maine, have made and invented a new and useful Im' provement in Vises; endl do hereby declare that the following is a full, elear,and exact description of the construction and operation of the same, reference' being .had to the annexed drawings making a partofvthis specification, in which- Iligure 1 is a sectional side elevation, wherein the `'elise is shown ina vertical` position, and

-, 4Figure 2, a plan, wherein thevise is shown ina hoi-L zontal position. l t My invention consists in providing the `foot of an ordinary vise'with a -ball-and-socket joint, the socket whereof is colnpressible, and in an appropriate device for compressing the same, whereby the ball may be' set o1; loosenedrtherein, the' object thereof being to *enable the .workman to arrange and hold the vise verticallygor at any angle of inclination in any direction above, and for Ya limited distance below, alhorizontal `plane bisecting the ball. t

Aj'lo enable others skilled in.4 the art to practice my invention, I describe the same asfollows:

i In the accompanying drawings, the parts marked@ a are the jaws of the vise, hinge d together near the `c and d are' the nut lz rnd'spring thereon, for

pressing andA opening the jaws;

elvis `a ball, in which is set the foot of the main jaw uw f j '.are'sections tia-halves of the s phericalsocket, in

.onefof wliich'fj", isforlnieclv a not'ch or recess, n, to allow y shanks i t" are drawn down into the conical hole` in- `plate g, compressing sectionsl f f', which set the ball e, and vthus hold the vise as arranged.

By turning the nut m back', the-ball e is loosened and the whole device may be partly or wholly turned aroundon the bench, the bolt formed of shanks 'i t" operating as a'pivot.

It is obvious that the 'socket may be formed of ltwo or more compressible sections, and that other arrangements of nuts and screws may be used for compressing t such sections without departing in the least from the principle of vmy invention.

Thus having described myimproved vise, Y

What I claim therein as new, and desire to secure by Letters Patent, is- Y,

The Acombination of the sectional socket f j" with conical,- sectional,and screw-threaded shank at', nut m, plate g, and vsocket-ball e, substantially as described and for the purpose set forth. A t I ROYAL J. CUSHINGr.v
